| There has been an increasing use of soil sampling grids for basing the recommendation of lime and fertilizers in a precision agriculture system in the west of Paraná, despising the undulating topography. Thus, this study aimed to evaluate the variability of soil fertility and the soybean Trabalho selecionado durante a VI Semana de Ciências Agrárias (VI SECIAGRA), realizada de 01 a 03/10/2012 yield on a farm in the west of Paraná which uses no-till system, previously divided into management units in a precision farming system. The experiment was conducted in eutroferric Oxisol characterized by being extremely loamy, in a property of 17.80 ha in Guaíra (Paraná, Brazil) cropped with soybeans in the... |

| Calcium silicate applied to the soil has an effect on plant nutrition since it is a source of silicon, calcium and magnesium. With the aim to evaluate the effect of doses of calcium silicate on soil chemical properties and on early development of corn, an experiment was conducted in a greenhouse, in pots containing eutroferric Oxisol, testing five rates of calcium silicate (0, 1.2; 2.4; 4.8 and 9.6 t ha-1) with four replications in a randomized complete block design. The levels of N, P, K, Ca and Mg in the plant shoot were evaluated, and, at the end of the experiment, shoot dry weight and plant height as well as Ca and Mg, and soil pH were also estimated. Shoot dry matter and plant height were not affected by fertilization with calcium silicate. The... |
